This is what I'm encountering...

Here's Pauline with the default Poser ground/hemisphere.

Try as I might, I cannot make this background go away without losing the shadows.. Here's Pauline with the ground/hemisphere made invisible ("visible" unchecked in the prop's properties tab):

I've tried with just Firefly in PP-11, and still cannot get the 'Shadow Catch Only' to work there, either. Is this a bug or am I just missing something? I'll be contacting SM about this as well, but just thought I'd toos it out and see if anyone here has any ideas.. Any Beta Testers out there?
